Marked all strings needing internationalization

These strings are now collected automagically in the file po/ledger.pot.
If you'd like to produce a translation, just run this command after
building Ledger:

    msginit -l LOCALE -o LANG.po -i po/ledger.pot

Where LOCALE is a string like de or en_GB, and LANG is a short
descriptive word for your language.

Then send me this .po file so I can commit it to the Ledger sources
(alternatively, you could maintain the file in a fork on GitHub), and
setup the build script to format and install your new message catalog
during a "make install".
